GREAT SOFTWARE. What’s that?

GREAT SOFTWARE.Just end-user things.

• Helps the user.

• Is software the user can rely on.

• Is easy to learn.

• Should be shiny. Really shiny.

• But how?

CONTINUOUS DELIVERY. But.. what is it?

• Your text goes here.

POKA-YOKE.Keep it simple, baka.

OUR STACK.Our highway to Production.

THE MANTRAS.A little bit better every day.

• Make it available to the end users as soon as possible.

• Small steps. Release every time code gets merged.

• Make it easy to correct missteps.

OUR APPROACH.Coming to non-functional terms.

• Testing, testing, testing.

• Code quality.

• Automate, automate, automate.

• Monitoring.

1. TESTING, TESTING, TESTING.When you’re in doubt, you didn’t test it.

• Unit-, integration-, regression- and end-to-end testing.

• When you fix a bug, you add the missing test.

2. CODE QUALITY.Build for today, but don’t get in the way of tomorrow.

• Have a consistent view on quality.

• Code reviews keep code great.

• Use and provide shared code.

3. AUTOMATE, AUTOMATE, AUTOMATE.Because the best developer is a lazy developer.

• No manual intervention beyond a code review. Ever.

• Aim for coded software, -testing and -infrastructure.

• Self-documents your entire process.

4. MONITORING.Because log files are overrated.

• Make your system visible.

• Continuously improve on your monitoring.

• We use Application Insights.
